Here, we demonstrated the single-step hydrothermal synthesis of VO2(M) nanocrystals (NCs). Thermochromic VO2(M) NCs were synthesized using phase-pure vanadium precursors obtained by size-selective purification. VO2(M) NCs exhibited enhanced luminous transmittance (55%) and solar modulation ability (18%), the value of the latter being one of the highest reported for hydrothermally synthesized VO2(M). W-doped VO2(M) NCs showed superior phase transition behaviors to those of undoped VO2(M) NCs, while the phase transition temperature was systematically reduced depending on the W-doping concentration. In addition, we experimentally demonstrated that integrating the W-doped VO2(M) into the window of a model house reduced the in-house temperature under daytime solar radiation, which exhibits the potential of our VO2(M) films for use in energy-saving window applications. |
